Method for binding a quire formed of folded sheets slipped into each other, characterized in that it consists in providing at least one cut through the sheets of the quire as of a short distance from the folding edge of the quire, whereby every cut through a sheet of the quire defines a lip extending mainly crosswise to the above-mentioned folding edge of the quire and which is connected to the quire with its far end turned towards the folding edge, and whereby said lip has a widening.

Apparatus and methods for cutting carpet pile are disclosed as including a clipper having a driver, a reciprocating blade and a fixed blade. The fixed blade and the reciprocating blade define an area there between. The fixed blade has a bore passing through the blade and into the area. A fluid supply, connected to the bore, supplies fluid through the fixed blade and into the area. A manifold, attached to the fixed blade, can be used to pass fluid through the fixed blade into the chamber. In such an embodiment, the manifold includes a passage communicating with the bore and the fluid supply. In another embodiment, an orientation mechanism is used to orient the carpet clipping head. In this embodiment, the orientation mechanism includes a base bracket and a pivot bracket. The pivot bracket is pivotally attached to the base bracket at a pivot point. The carpet clipping head is attached to the pivot bracket so that movement of the pivot bracket causes the carpet clipping head to pivot about the lead prong. In yet another embodiment, the carpet trimmer is attached to a computer controlled carrier platform. In such an embodiment, the carpet trimmer is spaced from the point at which the clipping blade contacts the pile before cutting the pile. In yet another embodiment, a pile orientation member is provided for orienting pile in the path of the clipper head so that the pile is oriented in a plane substantially perpendicular to the cutting plane.

The cutting die is made from strip steel and comprises a die blade having a cutting edge formed with sawteeth and chamfered surfaces extending along said cutting edge on opposite sides of said blade. To cut through a material which comprises a fabric having first filament portions extending in a predetermined direction and second filament portions extending transversely to said predetermined direction, said material is cut into at a plurality of discrete points which are spaced apart on an intended line of cut extending in said predetermined direction and said first filament portions which are disposed adjacent to said line of cut are pushed laterally away from said line of cut. At the same time, the cutting into said material is continued along said line of cut until said second filament portions extending across said line of cut have been severed.

A fur pelt slicing method and apparatus in which a pelt, held against a feed table surface by a bank of pins, is fed through a series of slitting knives rotating in the direction of pelt feed so that preselected portions of the pelt are left uncut. Also, the disclosure includes an out-feed table discharge portion by which transfer of the slit pelt to a retaining board is facilitated.

A rotary suture cutting apparatus includes a base having an upper resilient layer, and a cutting assembly. The cutting assembly includes a frame and a rotary cutting tool having a disk shaped circular blade. The cutting tool is slidably mounted to the frame and when moved from one end to the other of the frame, cleanly slices suture material clamped between the base and the cutting assembly without brooming, fraying or otherwise disporting the cut suture tip. A method of preparing cut suture lengths is also provided

Apparatus and method are disclosed for cutting paper pads to provide a paper pad which has a beveled edge. The apparatus includes a gripping assembly for gripping the pad and a positioning assembly for bending the pad intermediate its ends. A cutting assembly is provided for cutting the pad with a perpendicular cut while it is bent such that when the pad is returned to its original planar configuration, the cut edge will assume beveled configuration.
